Xevent ButtonReleaseMask in Xlib not working?

Hi,

I cant get the event for releasing mouse button (num 5) to work. Entering window (num 7) works and but I get nothing clicking the mouse buttons. I wrote this small program to test. What am I missing?

Code:

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#include <X11/Xlib.h>



int main(int argc, char **argv)

{

    Display *d;

    Window w;

    XEvent e;

    int s;

                

    d = XOpenDisplay(NULL);

    if (d == NULL)

    {

        fprintf(stderr, "Cannot open display\n");

        exit(1);

    }

    s = DefaultScreen(d);

    w = XCreateSimpleWindow(d, RootWindow(d, s), 10, 10, 200, 200, 1, BlackPixel(d, s), WhitePixel(d, s));

                    

    XSelectInput(d, w, ButtonReleaseMask|EnterWindowMask );

    XMapWindow(d, w);

 

    while (1)

    {

        XNextEvent(d, &e);

        printf("event: %d\n", e.type);

        if (e.type == ButtonRelease) {

            printf( "clicked.\n");

        }

    }

    return 0;

}

This is really irritating. I have been sitting all day to find this bug in my main program. And now i added ButtonPressMask and then it works. Totally illogical.

XSelectInput(d, w, ButtonPressMask|ButtonReleaseMask|EnterWindowMask );

Not even my mistake but a bug in Xlib.
